2008-03-08Port rombios32 code from bochs-bios.Kevin O'Connor10-17/+2691
This adds acpi, smbios, pci init, etc. Changes from original rombios32.c code: * Header file translation. * Use common functions already in code (eg, outb, memset, bios_printf, usleep) * Implement trampoline for disabling bios shadowing (rombios32 code actually runs in the 0xf0000 area). * Copy asm code from rombios32start.S to an asm() statement in C code.
